Hi again, I actually asked this same question while time ago, but had never got an answer for it, if anyone can help me, it would be most grateful. If possible, please leave some short explanation in your answer. Thanks
1. Suppose that the equilibrium
4NH3(g) + 3O2(g) = 2N2(g) + 6H2O(g)
were established by adding 0.30 mol NH3 and 0.40 mol oxygen to a 5.0 L container. If "y" moles of water are present at equilibrium, then what would the concentration of oxygen be...

Physical Chemistry
An empty tank is to be filled witha mixture of gas (nitrogen and propane) through a line at costant temperature and pressure. if fluid is to be considered adiabatic, determine the mass (kg) and the physical state of the fluid in the tank (final temperature). solve the problem by using equation of state Peng-Robinson and discuss the results.
a) line: nitrogen and propane 350K and 80 bar, final presure in the tank 60 bar.
